To all whom it may concern:

Be it known that I, Jonson S. PIXLEY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Signal-Lamps, of which the following is a specification.

This invention relates to a signal lamp whichcontains a lens of spheroidal, barrelshaped or cylindrical form which rests upon a circular seat in the base portion of the lamp on which it is held by a breast which bears upon the lens and is detachably secured to the upper ends of upright frame bars secured to the base.

The object vof this invention is to provide convenient, durable and ellicient means for securing the breast of the lamp to the upper ends of the frame bars and holding the lens on its seat.

In the accompanying drawings: Figure 1 is a sectional elevation of a signal lamp embodying the invention. Fig. 2 is a horizontal section through the lens on line 2-2 Fig. 1. Fig. 3 p is a horizontal section through the breast on line 3-3, Fig. 1, showing the breast in position for attachment to the frame bars. F ig.' l is a similar view, showing the breast attached to the frame bars. Fig. 5 is a fragmentary perspective view of the attaching means. Fig. 6 is a vertical section on line 6-6, Fig. 3. Fig. 7 is a fragmentary plan view ofthe bottom of the breast.

Like reference characters refer to like 7 parts in the several figures.

A represents the base of the lamp which is provided with a circular lens seat 10, preferably covered by a rubber gasket 11 or other suitable cushioning device.

13 represents upright frame bars secured at their lower ends to the base.

C' represents the oil font.

D represents the lens which is preferably composed of a number of upright sections arranged circumferentially sideby side on the seat 10 and tied together at thelr upper ends by a rubber gasket 12. The side edges of the sections are preferably provided with grooves 13 in which packing strips 14 are arranged.

E represents the breast which surrounds the upper end of the lens and bears upon the same and holds it upon its seat. The breast comprises an annular bottom plate 15 provided at its inner edge with an upwardly extending collar 16 which surrounds the upper end of the lens and bears against the same. The bottom plate 15 is provided with openings 17, one for each of the frame bars, which latter are provided at their upper ends with outwardly overhanging locking heads or hooks 18 adapted to be passed through these openings.

F represents an annular lock or looking ring which is arranged .upon' the bottom plate of the breast and is rotatable thereon. This lock is provided with openings 19 which coincide bottom plate but are elongated circumferentially and comprise an enlarged front porwith the openings 17 of the tion 20 suitable for passing the locking head of the frame bar through it and a narrow rear portion 21, suitable for receiving the contracted neck 22 of the frame bar. The annular lock is provided with inclined looking faces 23 arranged along the outer side of the narrow portion 21 of the openings. and

adapted to engage underneath the overhangmg portions of the locking heads. I

For connecting the breast. with the frame bars the annular lock is placedwith the large front portions 20 of its openings over the openings 17 of the bottom of the breast, as represnted in Fig. 3, and the heads of the frame bars passed through both sets of openings. The annular lock F is then turned on the bottom plate so as to engage the inclined locking faces 23 underneath. the overhanging heads, as represented in Figs. 1 andf), and wedge the breast downwardly until the parts are firmly secured together. The turning movement of the annular lock is preferably effected by means of a bar 24 which is inserted in openings 25 formed in an upwardly projecting collar 26 arranged at the inner edge of the annular lock and extending above the collar 16 of the breast.

The annular lock is preferably provided with a suitable detent for preventing accidental backward rotation of the lock, for instance a spring catch 27, which is arranged upon the lock and passes with its free end or head through a slot 28 in the lock and engages a serrated segment 29 on the bottom of the breast.

The lamp is provided with any suitable ventilating contrivance, for instance a hinged top 30 having air inlets 31 and a draft tube 32 leading to the outlet for the products of combustion.

are

lens and having openings upper ends with It is obvious that the herein described means for securing the breast to the frame bars can be used in connection with a solid or single-piece lens as well as with a sectional lens.

I claim as my invention:

1. The combination with a lamp base, .of

upright framebars secured at their lower ends to said base and provided at their" locking heads, a lens rest-- a breast bearing upon said through which said heads project, and a single rotatable means engaging said heads simultaneously for locking said breast to said bars, substantially as set forth.

2. The combination with a lamp base, of upright frame bars secured at their lower ends to said base and provided at their upper ends with looking heads, a breast ing on said base,

- having openings for the reception of said bars, and a rotatable lock arranged in said breast and engaging the heads of said bars,

substantially as set forth.

3. The combination with a lamp base, of upright frame bars secured at their lower ends to said base and provided at their upper ends with looking heads, a breast having openings in its bottom for the reception of said bars, and a rotatable lock arranged on the bottom of said breast and provided with locking inclines engaging the heads of said bars, substantially as set forth.

4. The combination with a lamp base, of upright frame bars secured at their lower ends to said base and provided at their upper ends with overhanging locking heads, a breast having openings in its bottom for the reception of said bars, and a'rotatable lock arranged on the bottom of the breast and :breast and breast With openings for the insertion of admission of said bars, a rotatable lock arranged in said breast and engaging said heads, and a detent for preventing backward rotation of saidlock, substantially as set forth. i

6. The combination with a lamp frame having upright bars and a breast, of a rotatable lock arranged in said breast and engaging said bars, said rotatable lock being provided with means for receiving an instrument for rotating the lock, substantially as set forth.

7 The combination with a lamp frame comprising upright bars and a breast having an inner collar, of a rotatable lock arranged in said breast outside of the collar thereof and engaging said, bars, said lock being provided With an upright collar arranged outside of the upright collar of the provided above the wall of the an instrument for turning the lock, substantially as set forth.

Witness my hand, this 16th day of September, 1912.
